Single Phase Induction Motor

The single-phase induction motor or engine consists of a single rotating phase in the stator and a rotating cage in the rotor. When phase one supply is connected to the stator winding, a magnetic field is generated. In the pulsating field, the rotor does not rotate due to inertia. So, a single-phase import motor does not start and requires some initial methods.

In alternating current, AC, theory, the voltage through an inductor leads the current by a phase angle of 90°. Complex numbers can help in this situation as when a real number is multiplied by i it rotates through 90° on the Argand diagram, with the magnitude remaining the same. This allows us to specify the impedance through an inductor as a complex number. This can be combined with a resistor to give a combined impedance of z = r + Li. If we have two such elements in a circuit, we can use complex numbers to determine the total impedance when they are in series and in parallel. In series Zt = Z1 + Z2 In Parallel Add the following two impedances (a) in series and (b) in parallel. Z1 = 4 + 3i and Z2 = 12 + 5i
